Hi,
Yes, this can be frustrating. However I also have trouble with my SuSE
9.2-compiled executables, since users report that on SuSE 10.1 an
additional library (compat-expat1-1.95.8-6) must be installed to avoid
an error linking with libexpat.so.0.
I would think though that building with a somewhat older system will
lead to better compatibility than building with the latest and greated
distro, since systems are more likely to be backward than forward
compatible.
Building on Debian Sarge results in executables that work on the last
couple of Ubuntu distributions. Hm, it looks like the Debian binary will
also work on SuSE 9.2, and FC 4 and FC 6, so I can probably get away
with a single Linux build.
When building on Linux I avoid use of standard C++ libraries and pass
the -lsupc+;+ flag to the linker to cut down on distribution-specific
libraries. -lsupc+;+ causes the executable to be built with only the
minimal C++ support, but might not work with all gcc versions or Unix
distributions (doesn't work on FreeBSD 5.4 for instance).
Compiling or testing on different distributions does of course get a lot
easier when you use VMware - highly recommended.
Regards,
Julian
